The queen in bed still closed her eyes and showed no sign of waking up.

They approached the vase carefully. The maid in waiting was still outside. Too loud would disturb her.

Stopped by the wooden frame, Yan Xiaoxi gave Nangong Lin a look, which seemed to say, I'll start the mechanism.

Nangong Lin nodded, wary of everything around him, and handed the vase to Yan Xiaoxi to operate.

Yan Xiaoxi put his hand on the vase and turned to the right. Just like last time, Qiang in front suddenly collapsed and stood on a staircase, which made her admire. The people who built this mechanism were really uncanny and amazing.

Nangong Lin took the lead in stepping up the stairs. He pushed Yan Xiaoxi behind him and told him, "follow me."

"OK." Yan Xiaoxi burst into tears and understood Nangong Lin's painstaking efforts. He was afraid that he would be in danger, so he stood in front of him, just didn't want her to be hurt.

For a moment, Yan Xiaoxi was also thinking, did he insist on coming here to help him or make trouble?

However, the feeling of waiting in the room would be more painful than her suffering time.

Instead of doing nothing, she would rather fight side by side with Nangong Lin. if anything happened, at least she had him around her. He was always by her side, making Yan Xiaoxi more fearless.

Yan Xiaoxi nervously followed Nangong Lin behind him. With the gradual deepening, the light inside was getting darker and darker. Nothing had happened for the time being. This situation was even more frightening.

The more safe it is, the more difficult it will be to avoid.

"Xiaolin, be careful." Yan Xiaoxi whispered, almost unable to see the Nangong Lin in front. The light completely disappeared at this time, making them fall into darkness.

She took out the fire fold on her body, blew a breath, lit it, lit it again, and the two people continued to move forward.

Nangong Lin turned back and frowned. He wanted to say something, but finally gave up. He wanted Yan Xiaoxi to wait for himself here. He immediately thought that she would never agree, so he had to give up the idea.

Yan Xiaoxi looked at Nangong Lin, who wanted to stop talking. He didn't feel confused and didn't ask. Instead, he walked forward more vigilantly.

"Here we are." through a long passage, they enter a room. The space here is small and the layout is quite simple. There is nothing except an ordinary desk.

There are four treasures of study on the desk. In addition, I can't see anything else.

Yan Xiaoxi and Nangong Lin looked at each other. They didn't expect to see such a strange scene.

Looking around, I couldn't see any trace of wood colored beads except the cold walls.

Isn't the wood color bead here?

"Xiao Lin?" Yan Xiaoxi really didn't understand what was going on?

"Take it easy." according to his experience, there are more mysteries in the simplest things than meat eyes. There must be a breakthrough somewhere.

You can't touch the things in here casually, otherwise you will touch the mechanism, making things more difficult.

"Said there was a piece of paper on the table." Yan Xiaoxi pointed to a place a few steps away.

They looked at each other and walked towards the table at the same time.

Yan Xiaoxi wanted to sit in a chair. He was pulled by Nangong Lin, who was quick in his eyes and hands, and warned, "don't touch anything here."

"En." Yan Xiaoxi nodded and turned to see Nangong Lin's eyes as deep as a pool of water, very sharp.

It seems that there are many chairs in front of her, but a dangerous cliff. Once it falls, it will die.

"There is nothing on this paper." Yan Xiaoxi said his doubts.

It's really weird to put such an empty rice paper on the long table without any hint or function.

Nangong Lin frowned. He also felt that the things in front of him were not in line with common sense.

What exactly does the person who designed this mechanism want to express?

"Xiao Lin, do you think it's strange?" Yan Xiaoxi felt something missing when he approached the table, but he didn't figure out what was missing.

Intuition is telling her that as long as you understand this, you may be able to find a breakthrough.

"Well." Nangong Lin nodded, and shared Yan Xiaoxi's heart. He also felt that the four treasures of the study in front of him were very strange. He swept the brushes and other items at the bottom of his eyes one by one. Suddenly, his pupils narrowed sharply and stayed in a blank space on the table.

Yes, that's it.

There is one important thing missing.

At the same time, Yan Xiaoxi also found a clue.

They said in unison, "inkstone."

There is paper, pen and ink on the desk, but there is no inkstone.

I wonder if there is any mystery in it?

"Xiao Lin, what do you think?" Yan Xiaoxi's eyes fixed firmly on a brush, which was not hung up, but placed on the desk, tilted and pointed to a place in the room.

When I looked in the direction I pointed, I saw that there was a small hole, a very small hole. If I didn't observe it carefully, it would be difficult to find it. She and Nangong Lin both knew martial arts and could easily find what ordinary people neglected.

"Look there?" obviously, Nangong Lin also noticed this and found the same seat as Yan Xiaoxi.

With that, he stepped forward and stopped in front of the small hole.

"This is a keyhole," Nangong Lin murmured.

Hearing this, Yan Xiaoxi immediately aroused her curiosity. She moved to Nangong Lin's side and looked down at the small hole carefully. Sure enough, as he said, there was a lock that needed a key to open.

So? Where are the wooden beads?

But where are the keys?

"Maybe the key is on the desk?" there was no place in the whole room except the desk.

However, a few simple things came and went on the desk. She and Nangong Lin also looked at them. They didn't think there was anything like a key.

"Go and have a look." in order to find the key, the two returned to their desks.

"Xiao Lin, do you see anything?" Yan Xiaoxi felt that his head was full of brush, paper and ink. Even if he looked carefully, he didn't find any clues.

Nangong Lin shook his head. Like Yan Xiaoxi, he didn't see a clue.

Yan Xiaoxi sighed and subconsciously sat on the chair. At the moment her ass fell, she realized that she was in trouble again. She quickly looked in the direction of Nangong Lin and wanted to ask him what to do?

When her body was pressed on the chair, she only heard the sound of moving to the mechanism. In a moment, the empty room changed. The desk in front of her disappeared out of thin air. There was an octagonal table in the center with a teapot and a teacup on it. Several inexplicable paintings were hung around the wall. Everything became as fast as lightning, It forms the picture in front of you.

"Xiao Lin, this" she didn't know what mechanism she touched.

I don't feel any danger for the time being. Is it a blessing in disguise?

If he hadn't seen it with his own eyes, Nangong Lin would not believe it. In the blink of an eye, he could completely change the room. He also met such a mechanism for the first time.

He held Yan Xiaoxi's hand and tried to keep her calm. The danger had not come at that moment. Since they were still standing here safely, it meant that Yan Xiaoxi started not the danger, but the breakthrough to find the key.

The previous small hole was still in place without proper deviation, which made Nangong Lin more sure of his mind.

"Xi'er, look around and you may find something." the room just now was empty and there was no clue to follow. On the contrary, the four paintings on the wall took a lot of time to figure out.

Yan Xiaoxi nodded and cooperated with Nangong Lin in a tacit way. She didn't understand these things and gave them to him. Her choice was to check the octagonal table in the middle.

There is a teapot on it. Maybe the clue is tea. We can't let go of any clues. It's about eating and drinking. It's her specialty.

With Nangong Lin's warning, Yan Xiaoxi didn't dare to touch things easily. She was afraid that she was lucky last time. Who knows if she will be so lucky next time.

She stood around, paying close attention to the patterns of the teapot and teacup. Through her understanding, there was nothing suspicious. This kind of teacup was very common in the imperial palace.

Then she leaned over, put her head close to the mouth of the teapot, and carefully smelled the tea inside. Because it had been put for a long time, the taste was very weak and didn't give her any hint.

At this time, Nangong Lin swam back and forth in front of the four paintings. Looking from Yan Xiaoxi's line of sight, there was a valiant man in front, holding the sword and riding on the horse, expressionless and unable to see any inner thoughts.

Looking to the upper left, it was a place where flowers were in full bloom. A young girl was planting flowers with a basket. Beside her, there were common tools and a smile. People couldn't help feeling faster.

Looking down, Yan Xiaoxi was shocked by the third painting. It was dark, there was nothing on the paper, and it was covered with black color. She saw such a strange painting for the first time.

"Xiao Lin, do you understand?" Yan Xiaoxi asked when he came to Nangong Lin.

Nangong Lin understood that Yan Xiaoxi was referring to the third painting. When he looked at it at first, he also felt quite strange. Therefore, he observed it back and forth, but he didn't understand the meaning.

Seeing Nangong Lin gradually distracted, Yan Xiaoxi was not ready to disturb him. Then she looked at the fourth painting, which was a very simple landscape painting. Even if she didn't understand painting, she could see that her skills were extraordinary and could not be achieved by ordinary people.

The four paintings appeared in his mind one by one. Yan Xiaoxi calmed down and wanted to find something related inside. After thinking for a long time, he didn't find anything. Nangong Lin around him was still silent and didn't know what he was thinking.

Suddenly, her clear eyes suddenly stopped on the second picture.
